Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Sans Souci faces a notable risk of flooding due to its low-lying coastal location and proximity to Botany Bay. Sea level rise and increased rainfall intensity are expected to exacerbate this risk.
- Bushfire
- The risk of bushfire in Sans Souci is relatively low due to its urban environment and limited vegetation. However, surrounding areas with more bushland pose a potential threat.
- Heat
- Sans Souci experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This poses a risk to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2219
- Highest high-risk exposure
- 15.5% of land (bushfire)
Climate Safety Analysis
Sans Souci in New South Wales has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Sans Souci's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Sans Souci is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Sans Souci including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Sans Souci (postcode 2219) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (15.5% of land in high-risk zones), riverine flood (7.8% of land in high-risk zones), surface flood (6.8% of land in high-risk zones). Exposure is not uniform across Sans Souci — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
